Claims.

This invention relates to improvements in napkin dispensers.

It is the primary object of the invention to provide a novel, simple, and inexpensive and sanitary device for mechanically projecting a single paper napkin from a stack of such napkins which is otherwise fully housed andprotected from contact with the fingers of the user.

In the past, napkin dispensers operating mechanically have usually involved relatively complex mechanisms including cams, rollers, and frequently gears and the like. It is an important object of the present invention to provide a structure which is so simple as to include practically nothing to get out of order and to accomplish the discharge of a single napkin accurately without danger of clogging and yet without requiring a single roller or cam for its operation.

It is a further object of the invention to provide a novel and improved dispenser which will satisfactorily dispense a square folded napkin. Most dispensers require for their operation that the napkin be folded into oblong form with projecting edges, folds or corners, to enable the napkin to be grasped by the operator. The present dispenser may be made practically as cheaply as a dispenser in which the napkins are delivered purely manually and yet it enables the use of the desirable quarter folded napkin Without any corners or edges exposed to the grasp.

Other objects will be apparent to those skilled in the art upon study of the following disclosure of the invention.

In the drawing:

Fig. 1 is a view in perspective of our improved napkin dispenser as it appears when closed and in condition for use.

Fig. 2 is a view of the dispenser in perspective as it appears with the front cover lowered to expose its content of napkins.

Fig. 3 is an enlarged detail view in cross section through the dispenser from front to rear.

Fig. 4 is a view similar to Fig. 3 showing the first step in the process of dispensing a, napkin.

Fig. 5 is a view similar to Figs. 3 and 4 showing the first napkin of the stack projected from the container in a position to be grasped by the operator.

Like parts are identified by the same reference characters throughout the several views.

The dispenser comprises a case 5 provided with a back 6 and a correspondingly shaped front wall at 1 which is hinged to constitute a door through which access may be had to the interior of the case for replenishing the supply of napkins 8 therein. t

Hingedly connected at 9 to the back 6 of the case is a channel-shaped false bottom l0 having upstanding flanges at H spaced to receive and support the quarter folded napkins 8 which stand of the napkins 8 comprising the stack within the dispenser. One or more links I! connect the flanges l l of the false bottom ID with the flanges I6 of the false top l5 whereby the false bottom and the false top move in unison upon their respective hinges 9 and 14. A compression spring at l8 between the bottom of the case and the false bottom l0 supports the false bottom and its charge of napkins 8 in the raised position in which the parts are illustrated in Fig. 3 and Fig. 4. I

Another compression spring at I9 exerts a forward thrust on the conventional follower plate 20 which impels the napkins 8 toward the front of the cabinet.

Connected with the case 5 and spaced forwardly from the margin 2! of its top are the stop plates 22 at either side of the case having hearing surfaces against which the side margins of the napkins 8 are pressed by the follower plate 20 under pressure of spring l9. The space intervening between the stop plates 22 is normally spanned by a plate 23 carried by the front wall or door 1 of the cabinet which may lie against or between the stop plates 22 when the door is closed,

thereby presenting a substantially continuous or only slightly ofiset smooth surface across the front of the cabinet against which the first napkin 8 rests.

The front wall or door of the cabinet 1 has a notch at 24 in which the marginal flange of the door is so spaced from the margin 2| of the case as to provide a dispensing slot approximately equal in width to the thickness of a quarter folded napkin 8. Directly beneath this slot and in the lower portion of the cabinet is a bar or wall 25 which extends across the cabinet between the stop plates 22 and just within the vertical space occupied by such plates, said bar preferably being notched to accommodate a handle 26 which projects from the false bottom It through a slot 21 in the front wall or door 7. The slot 2'! is preferably .T-shaped so that the door clears the handle 26 when opened or closed and yet clearance is afforded for the vertical movement of the handle.

It will be noted in Fig. 3 that the false bottom l0 does not reach the plane of the bar or wall 25 or that in which the inner bearing surfaces of the stop plates 22 and 23 are located. Consequently, in the downward movement of the false bottom 10, it readily clears the bar 25.

While any desired means may be employed for within the front or door of the cabinet, and a rod 29 extending through such ears supports a pivoted yoke 30 which is provided at 3| with a manually operable lever and is provided at 32 with hooks engageable with the edges 33 of the stop plates 22 which are provided by notching the stop plates.

The operation of the mechanism is as follows:

With a stack of quarter folded napkins 8 mounted between the false bottom l and the false top l and under pressure of a follower plate 20, the foremost napkin of the stack will be pressed by the stack against the stop plates 22 of the case and the intervening stop plate 23 of the door I. The stop plates 22 and 23 are smoothly finished interiorly so as to minimize frictional resistance of the stop plates to the sliding of the folded napkins thereon. Consequently substantially the only vertical support to prevent the foremost napkin of the stack from sliding down is provided by the frictional contact of the foremost napkin with the second napkin of the stack, the second napkin being supported on the false bottom Hi.

When the operator presses downwardly on the handle 26, the false bottom and the false top, connected by the link ll, move downwardly in unison, carrying the stack of napkins bodily in a downward direction. Since the coefficient of friction of the stop plates 22 and 23 is very low, the first napkin would readily move downwardly so far as the stop plates are concerned, but the upper margin of the stationary bar 25 is engaged by the first napkin, causing such napkin to remain approximately stationary while the rest of the stack moves downwardly between the spring supported false bottom and the-false top linked thereto.

The stop plates 22 and the inset door plate 23 cooperate to form a thrust bearing member or wall against which the folded napkins are pressed by the spring actuated follower plate 29 to feed them forwardly and hold'them in a substantially uprightposition, with the leading napkin in registry with the slot or notch 24, between the slot and the displacement bar or 'wall 25. The false bottom It! and the falsetop 15, with their pivotal connections and linkage, constitute a reciprocatory carrier for napkins or similar articles and hold such articles in such a position that the follower plate presses the leading article against the thrust bearing member or wall, with its fiat front surface in contact with the wall, the article being thus held in registry with the delivery slot.

When the operator releases the lever 26 or permits it to move upwardly under pressure 'of the spring 43, the false bottom and the false top, connected by link I1, carry the entire stack upwardly including the first napkin which is now somewhat above the level of the remainder of the stack and remains in its relatively elevated position because of the fact that its frictional engagement with the second napkin of the series is much more tenacious than the frictional resistance offered by the relatively smooth stop'plates 22 and 23.

As a result, the upward movement of the stack carries with it the somewhat elevated first napkin 8; thereby projecting the first napkin through the dispensing slot as shown in Fig. 5.

It will be apparent that many changes can be made in. the specific design of the parts without deviating from the essence of the invention as herein disclosed.

It is immaterial in a broad sense whether the support for the stack of napkins moves bodily or hingedly in the manner disclosed. It is likewise immaterialin a broad sense whether the dispensing slot is above or below, since the device will function in either direction. Many changes in the specific design of the cabinet and its parts will suggest themselves to those skilled in the art.

We claim:
